Summary. Semen from a male dolphin in captivity was collected by electroejaculation and frozen to −176°C. Sperm motility was excellent after thawing 10 days later. Electron microscopy showed 14–16 parallel ridges in the post-acrosomal region and two types of mitochondria in the mid-piece. The spermatozoa were capable of fusing with zona-free hamster eggs only after preincubation for 2 h, suggesting the need for sperm capacitation and acrosome reaction before fertilization in this species.
